Your Grade Point Average (GPA) is a standardized measure of your academic performance. Most US colleges use a 4.0 scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Plus and minus grades adjust these values (e.g., A- = 3.7, B+ = 3.3).
The GPA Formula
GPA = Total Quality Points / Total Credit Hours
Where Quality Points = Credit Hours x Grade Value. For example, if you earned an A (4.0) in a 3-credit course, that's 12 quality points. A B+ (3.3) in a 4-credit course is 13.2 quality points. Add up all quality points, divide by total credits, and you have your GPA.

- Enter the credit hours for each course (usually 3 or 4).

GPA Calculator FAQ
What is a good college GPA?
A GPA of 3.0 or above (B average) is generally considered good. A 3.5+ is excellent and puts you in the top tier for graduate school applications. A 2.0 is the minimum most schools require to stay in good academic standing.
How is GPA calculated?
GPA is calculated by multiplying each course's grade points by its credit hours, summing those products, and dividing by total credit hours. Formula: GPA = Sum(credits x grade points) / Sum(credits). For example, an A (4.0) in a 3-credit course = 12 quality points.
Does this calculator work for weighted GPA?
Yes. Use the cumulative GPA section to combine your previous GPA with your current semester courses. This gives you a weighted calculation that accounts for all your credits across semesters.
What's the difference between semester GPA and cumulative GPA?
Semester GPA is calculated from only your current semester courses. Cumulative GPA includes all courses across all semesters. Use the "Previous GPA" and "Previous Credits" fields to calculate your cumulative GPA.
